CULTIVATOR.

' Canton, in the county of Fulton and State of Illinois, have inventedcertain new and useful Improvements in Cultivators, of which thefollowing is a specification, reference being had to the accompanyingdrawings. My invention relates to cultivators, and its object is toprovide a new and improved construction by which'the wheels may beangled and the gangs shifted laterally simultaneously by the same levermovement, by

which the gangs may be raised or lowered either separately or 'in'pairs,by which the wheels maybe shifted backward relative to the framesimultaneously with the raising of the gangs in pairsby means of asingle layer, by which the wheels may be automatically locked againstangling and the gangs against lateral. movement when the gangs areraised or when the wheels are shifted to their rearmost position, and byJWhlCll the wheels may be shifted laterally 'for diflercnt widthsbetween the rows to be cultivated." I accomplish this object by themeans shown in the drawings and herein after specifically described.That which I believe to be new will be set forth in the claims. I 1 v Inthe draw1ngs:*l l1gure 1 is a side elevation of a cultivator embodyingmy improvements. with one of the wheels removed for the sakeof'clearness of illustration.

lteferringto the drawings :20 indicates cariying wheels mounted uponspindles Qt. llachsspindleQl is provided with a vertical portion 22 (see8). which, at its upper end, is provided with a torward ly-projectingportion 533 (see Fig, 5), the three parts being formed ii'iteg'ral. Eachspindle member 21 is rcvolubly mounted in a vertical sleeve 24., saidsleeve being cut away for the greater portion of its length at its frontside 'to enable the integral spindle member to be inserted.

As shown in Fig. 5, the lower end of the sleeve that is not cut awayisenlarged to receive the lower end of a block (see Fig. (3) which is usedto take the place of the cut-out portion of the slceye to hold thespindle ll'lQl'l'lllQI' 21 in position, said block being secured inplace at its upper end by a bolt passing through it and through loss 26on the sleeve. At the pointwhere the torwardly-projccting portion 23emerges from the sleeve 24, sufiicient play is. provided to enable thepart22 to be rotated to a limited extent in the sleeve 24. by thelateral movement of the front end of the part 23, thus angling thewheels relative to the machine. as will 'bereadily understood.

As shown in Fig. the sleeve it is part oi a bracket comprising also aho; izontal bar 27, a diagonal bar 28. and horizontal transversesleeves21) and 30, one of suchbi'avkcts being provided at each side of themachine, as shown in Fig. 4.. 31 indicates a tubular bauextcnding "fromside to side of the machine. each end-being inserted in one of thesleeves 30 so as to slide treelyiherein. 32 indicates rods. one at eachside of the machine, each adapted to slideircely at its inner end insaid tubular bar 3l and each bqdted or otherwise secured. at its outerend viding for a free and easy movement of each bracket laterallyrelative to the tubular bar 31, as will be seen. The rod 32, tubularbars 31, spindle members 21 and the brackets by which such parts areconnected, constitute in effect a wheel-arch pivoted relative to theframe. 33 indicates two brackets one of which is securely attached uponeach end of the tubular bar 31 by means of a wedge bolt 33 34: indicateshounds which are bolted at their rear ends to the brackets 33 and attheir forward ends to the tongue 35, as shown inFig. 2. 36 indicatesseat-supporting bars which are, by means of angle irons 37, secured attheir forward ends to the crossbar 50 hereinafter referred to, extendingrearwardly therefrom and resting upon the tubular bar 31. Secured to therear ends of these bars 36 is a seat 38 of any suitable type.

As shown in Figs. and 7, the forward ends of the portions 23 of thespindle members are pivotally connected between two parallel transversebars 39 whereby by movement of the bars 39 longitudinally of themselvesthe wheels may be simultaneously angled.

As best'shown in Figs. 13 and 1d, each of the brackets33 is provided onits rear and "lower side with a circumferential flange or rib 40. 41indicates a block grooved on its front face to engage said rib &0. Theseblocks ll are adapted to be bolted to the horizontal portions 27 of thebrackets which connect the wheel spindles to the frame of the machineand) thus hold said brackets against lateralmovement, at the same timepermitting a limited swinging movement of the bracket relative to thetubular bar 81 upon which the brackets 33 are fast.

As shown in Figs. 5 and 8, the bars 39 are provided with a series ofholes through any one of which the bolt that connects the portions 23thereto may be passed, and the hori zontal port-ions 27 of the bracketshave a like number of holes through the corresponding one of whichihebolt which secures the block 41 in position may be passed. By this meansthe wheels may be readily and .quickly shifted laterally for understood.

rows of different widths, as will be readily (see Fig. 4) havingout-turned horizontal 4-4: indicates yokes revolnloly mounted upon thehorizonta-l portions 43, attached to which are shovel beams 45 of anyapproved type, carrying shovels 46. 47 indicates sleeves mounted uponthe horizontal portions 43 between'the arms of the yokes Secured attheir lower ends to the sleeves 47, each being pivoted between earsformed on one of the sleeves,

itch pivoted between formed on 42 indicates the shovel arch two pushhars 48, the upper ends or" the bottoms of the braclwls 33, as shown inFigs. 5 and 13. i9 indicates rods hooked at their lower ends in cars onsaid sleeves ll, as best shown in Fig. 1, and hooked at their upper endsin suitable openings in the transverse L-shaped bar 50 which is boltedat its center to the tongue and secured near its ends to the hounds 34.These two parts -18 and 49 which support the lower ends of the arch 4?.permit lateral movement of the arch. Upon the upper horizontal portionof the shovel. arch 42 (see Fig. is a split sleeve 51 which is adaptedto be clamped securely inplace by means of abolt. Extending rearwardlyfrom this sleeve 51 is a short arm 52 to which is attached bymeans of ahori- Zontal pivot a plate This plate is socured at its rear end betweenthe transverse bars 39 by bolts, the distance between which bars 39 issullicient to provide for some little play between the plate and thebars 39 so that they may be either held in alinement in their normalposition or may be angled slightly relative to each other when the.whecls are shifted backward in the frame when the gangs are raised inpairs, us hereinafter described.

it will be readily understood from the above description that when thebars ll!) are shifted longitudinally of themselves in angling thewheels, as above described, they will carry with them to one side or theother of the machine the plate 53 and arch 51-52. which in turn willthrow the front ends oi the shovel beams (oi-respondingly to that side.

Revolubly mounted upon the tubular bars 31 and depending therefrom (seeFig. 8), are two brackets 54: secured against lateral movementby'collars 55. Bolted to these brackets 5% are two foot-levers 5G-57,each provided with a treadle 58. Each bracket 54 is provided with aperforated lug 59 on its front face, intowhich the rear cud of apush-bar 60 is hooked, the front end of which bar 60 is provided with anopening through which opening and through suitable openings in the bars39 at some little distance farther toward the side of the 1nachine thanthe bracket 54 is passed a boltv or rivet.

From the above description, it is apparentthat by pushing the footlever57 forward the bars 39 are caused to shift to the left in Fig. 7,'thuscarrying the arch 42 to the left and at the same time angling the wheelsto carry the machine to the left. as hereinabove described. Pressureupon the foot-lever 56 serves thereupon to return the parts to thenormal position (shown in Fig.

4), and further pressure upon the foot-lever with an ear 63 which isbolted to the transverse bar 50.

64 indicates a bracket (see Fig. 12) which is provided with a boss 65adapted to fit and rotate in, a circular opening in the bracket 61,-passing centrally through which boss is one centrally through a similarcircular boss on asleeve 67 which fits and rotates in a circular openingin a bracket 68 which is bolted to the hound 34 at the opposite side ofthe m-achinefrom the bracket 61. The bracket .c with a hahdle 64 andsleev'e67 are bolted rigidly to the rock-shaft 66, so that the bossesare held firmly in contact with the circular openings in the brackets 61and 68 so as .to rotate therein, the rock-shaft also being thus r0-tatable in said brackets.

69 indicates two brackets non-rotatably secured on the rock-shaft 66.

70-71 indicate levers which are bolted to brackets 72 that are pivotallymounted on bosses 69 formed integral with said,

brackets '69, each of which levers is provided portion 7 3, a latch '74,springactuated plunger 75, and rod 76 connecting the plunger and latch,which. plungers are adapted to engage the teeth of racks 77 .car-

' separately at any at their upper ends against collars 85 which ried bysaid brackets 69 to set the levers desired position relative to thebrackets. Each of the brackets 7 2 has on its front face a shortdistance above the j pivot point of the bracket 72 upon the bracket 69 aperforated lug. 78 to which is,

attached one end of a coiled spring 79 the other end of which is'adjustably attached to an arm 80 depending from the transverse bar 50,said spring tending to hold said bracket 72 in its forward'turnedposition.

' On the ear face of each bracket 72 is a perforateo lug 81 to which isattached the upper end of a pull-rod 82. The lower ends of. the rods82pass through holes in brackets 83 secured upon the gangs 4.5, beingslida ble therein but prevented from withdrawal therefrom by heads 82 ontheir lower ends. Upon each rod 82 is located a compression spring 84which bears at its' lower end against the bracket 83. These springs bearare secured by set-screws upon the rods 82, by which construction-thespring may be caused to press more-or less heavilyupon' the gangs asdesired.

From the above description, it will be seen that when either of thelevers 76er- 71 is moved forward, through the medium of the pull-rod 82,the gang connected tosuch lever is raised, such raising of the gang be-.ing assisted by the pull of the extended spring-79, the strength of,which canbe adend of asquare rock-shaft 66. 'The other end of.therock-shaft 66 passes justed, as above described, It will also be seenthat when the lever is moved backward to permit the gang to be in itslowered p'o sition, the spring 84 serves to hold the gang yieldinglystrength of this-spring also being adapted ,to be adjusted, asdescribed.

Coming now to the means for raising the gangs in pairs and for shiftingthe wheels backward and forward relative to the frame,

85 indicates a leverbolted to the bracket 64 whereby the rock-shaft 66is adapted to be turned. The lever 85 is provided with the usual handleportion 86, latch 87, springactuatcd plunger 88, and rod 89 connectingthe latch and the plunger.

' 90 indicates a flange on the bracket 61,.

provided with two notches which the plunger 88 is adapted .to engage tohold the lever in position,'as will be readily understood.

91 indicates arms depending from the bracket 64 and sleeve 67, tothedower ends of which are pivotally attached heads, 92 into which arescrew-threaded the front ends of rods 93, the rear ends of which arehooked in perforated lugs 94 on the front faces of the sleeves 241 Fromthe above description it will be seen that when-the lever 85 is movedupward from the position shown in; ll 1, for example, the rock-shaft 66will bero- .ta'ted clockwise in said figure, causing'the levers and 71to mov forward, raisin-g both of the gangs 45, both of the springs 79assisting in the operation. At the same time, through the medium ofthe.rods $13, the sleeves 24 and therefore the axles 21 will be movedbackward relative to the frame so as to'compensatefor the additionalweight of the gangs at the back part of the machine and to'maintain theproper balance It will be of the machine on the wheels. seen that if thelever 85 be moved upward while the machine is still in motion, theoperation will be greatly assisted by the tendency of the wheels to stopand the con-' sequent backward pull upon the rods 93.

Each of the brackets 54 is ,provided with an arm 95 rising therefrom andprovided at .its upper end with a'horizontal stud 96, extending over theseat-supporting bar 36 at that side of the machine. Asshown in Figs. 1and 4-, when the gangs are in lowered position and the wheels areconsein. the ground, the effective quently in their foremost position,the studs 96 are some little distance above the bars 36. When, however,the 'gangs are raised by means-of thfe leve ,85 and the wheels'are, ashas been gescribediat the same time shifted'loackwar' re lative to theframe,- the. bars 39 are lowered and: shifted slightly backward, asse'err'by acomparisonof Figs; 1

and, 3, .c'ausinga corresponding change in position of the'push-rods 60and. brackets ends of said blocks in position,

&

5st. The result is that each of the studs 96 is brought into contactwith one of the bars 36, thus holding the brackets 5 1; against turningand preventing any angling of the wheels or lateral shifting of thegangs while the wheels are kept in their rearmost position, this resultbeing attained automatically without any effort on the part of theoperator. Any forward push of one of the foot levers, as 56, tends tolift its part 95, but also tends to cause the other lever 57 to movebackward which is prevented. by the contact of the other part 95 .withthe frame bar 34. I

So far as I am aware, no one in the art has heretofore provided meansfor automatically locking the wheels of this type of machine againstangling or the gangs against lateral shifting when the gangs are raised,andgthe claims are therefore to be construed accordingly.
